• The AMT Bridle™
    Nasal Tube Retaining System

    Every Tube, Every Time!

Consistent nutritional support is essential to providing the best possible patient outcomes. Inadvertent feeding tube dislodgement interrupts nutrition and medication delivery. The AMT Bridle system dramatically reduces feeding tube pullouts, resulting in improved caloric intake.

The AMT Bridle™ is available in two styles to fit patients of all ages and sizes.

Select A Device Below:

Inadequately secured nasal tubes expose patients to risks including:

– Aspiration
– Pneumothorax
– Radiographic exposure
– Early and unnecessary transition to PEG/TPN
– Skin breakdown due to adhesive devices
– Sinusitis
– Pressure necrosis
– Interruptions to nutritional support
– More frequent replacement procedure

The AMT Bridle Nasal Tube Retaining System has been shown to:

– Reduce cost of extended hospital stay due to sub-optimal nutrition
– Reduce cost of clinicians’ time spent replacing nasal tubes
– Reduce cost of new nasal tube, formula and supplies
– Reduce cost of secondary x-ray or fluoroscopy
– Reduce unreimbursed expenses under managed care

Why the AMT Bridle™?

Comfort for ALL Sizes

The AMT Bridle System secures the largest range of tube sizes for pediatrics and adults. Available in sizes 5-18F. For optimal comfort and ease of placement the AMT Bridle System includes lubricant and does not use ANY adhesive tape!

Nutritional Advantage

Using the AMT Bridle System secures the flow of nutritional support to the patient, which plays an important role in management of nutritional deficiencies and is part of the standard of care for critically ill patients.

Cost Savings

Tube replacement is expensive and decreases clinician productivity. Studies suggest the incidence of unintentional tube removal is 40%.

How to Place the AMT Bridle™ System

The AMT Bridle is easily placed using magnets to draw umbilical tape through the nasopharynx; in one nare, around the vomer bone and out the other nare, then securing it to the nasal tube with a clip.

Frequently Asked Questions:

How does the AMT Bridle System save money for the patient and hospital?

Optimal Nutrition – Optimal Recovery – It is generally believed that early aggressive enteral feeding facilitates faster patient healing with a resultant decrease in ICU and hospital stays. Use of the AMT Bridle™ minimizes interruption of tube feedings, thereby enhancing patient nutrition. Although difficult to measure, this factor may translate into the greatest cost saving and health benefit of all Bridle features.

Savings on Tubes, X-Rays, and Nursing Time – Use of the AMT Bridle System results in a significant cost savings, especially when every tube is Bridled. A study conducted at the University of Pittsburgh Medical Center estimated that using the Bridle for all their tubes (1440 per year) would result in 275 fewer tubes, 330 fewer X-Rays, and 45 fewer nurse-days (Gunn, et. al., JPEN Vol 33, Feb 2009).

Savings on Enteral Nutrition Formula – If a tube is pulled out, replacement can take several hours which can result in the need to discard expensive enteral nutrition formula. Use of the Bridle dramatically reduces pull-outs, so waste is also minimized.

Savings on Staff Time and Laundry Cost – If a tube is pulled completely out, the formula is pumped onto the patient’s bed. The result is a messy cleanup which wastes staff time and adds to laundry costs. Bridling prevents most pull outs so these expenses are avoided.

  • Cost of Nursing Time: $28.00
  • Approximate Total Cost: $429.00
  • Approximate cost to replace 2 feeding tubes: $858.00
  • Approximate cost to replace 3 feeding tubes: $1,287.00

*Information taken from multiple sources

Is there an increased risk of infection or sinusitis with the AMT Bridle System?

To date, hundreds of thousands of AMT Bridles have been placed in over hundreds of institutions and there has been no documented increase of incidents of sinusitis associated with the use of the AMT Bridle.

Will the AMT Bridle device damage the nasal septum?

All tubes passing through the nasal cavity can irritate the nasal mucosa as can the Bridle umbilical tape. The Bridle tape should be lubricated before placement. The Bridle tape should rest without tension in the nose when properly applied. Any minor irritation of the nasal mucosa will heal rapidly when the Bridle and tube(s) are removed.

To date, hundreds of thousands of AMT Bridles have been placed in over hundreds of institutions.

What happens if the patient pulls on the AMT Bridle device?

If a patient pulls on the tube secured with the Bridle, they will create pressure on the vomer bone at the back of the nasal septum/vomer bone, which will cause discomfort. This negative reinforcement will deter most patients from pulling further on their tube. Despite this, some patients will continue to pull. The increased force on the tube will cause the outside diameter of the feeding tube to narrow and slip through the clamp before damage to the vomer bone at the back of the nasal septum occurs.

To date, hundreds of thousands of AMT Bridles have been placed in over hundreds of institutions.

How long can the Bridle stay in?

The Bridle is only cleared for up to 30 days of continuous use.

Why shouldn't I use a "homemade" bridle?

Safety – The AMT Bridle clip is designed to allow some slipping should a patient pull so hard that they might hurt themselves. To date, over hundreds of thousands of AMT Bridles have been placed in hundreds of institutions.

Patient Comfort – The magnetic retrieval system allows for a gag-free interface with the patient since you are not reaching into their mouth, as is required in the homemade technique.

Time Savings – The AMT Bridle can be placed in under a minute. Published studies on unplanned tube removal suggest an incidence of 40%. In the event of unintentional dislodgement or migration, the Bridle can save hours in reinsertion time.*

Optimal Materials – A clinical study, not supported by AMT, was performed by Seder and Janczyk (Nutr. Clin. Pract., Dec 2008) that determined the use of red rubber catheters in homemade bridles resulted in 4 cases of nasal ulceration per 800 tube feeding days. However, they observed no ulceration with umbilical tape. The rate of tube pull out was also decreased with the umbilical tape. All materials used in the AMT Bridle have been specifically chosen to optimize performance and safety.

What is the safety record of the AMT Bridle System?

Bridle techniques have been used for more than 20 years. The AMT Bridle system, in use for over ten years, builds on the safety record of the “homemade” version by making the loop around the vomer bone easy to create.

Why can't the AMT Bridle System be re-used?

The AMT Bridle is designed to be a single-use disposable product.

Will the AMT Bridle System magnets disturb a pacemaker?

The AMT Bridle magnets are used only to create the loop around the vomer and do not stay in place; additionally, they are very small but to date there have been no incidences to pacemakers. Consult your physician.
